Insulation questions, answered by experts

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

Interior walls don't require insulation. However, there are a couple of reasons you may consider adding it in some situations. Insulation in interior walls is excellent for sound-dampening between rooms and can help maintain a regulated temperature in insulated rooms by lowering the heat transfer between adjacent areas of the home.

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

Ductwork insulation in the crawl space is a simple add-on if you are hiring someone to insulate the entire crawl space already. Separately, it is only a few hours of work. The investment is nothing compared to the return since uninsulated ducts can lose up to 30% of their heating and cooling efficiency.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.
